BEAD-SF- Wnof MACHINE. s

ladap'ted to attach' any Vsmall articles such as beads' which arevstrin'ig yupon a thread. to a fabric, by means of `stitches formed withthe thread on Whichvthe articles are strung. ln the followingdescription and claims l'use the term beadsin the broad sense to coverany formof article which may be vstrung on a thread.

Inpl.V S. Patent VNo. 1,041,780 dated October 22, 1912, l showed andVdescribeda machineV for attaching beads or similar articles to fabric byformingjstit'ches in the fabric with the thread on which the beads arestrung. That machine is .adapted to attach the beads Without the .useVof separating threads Wound spirally aroundV the V:beadsv and originalthread and Without the use'of a separate or stitching thread in additionto the one on which the beads are originally strung.Y In U. S. PatentNo. 1,073,344 dated September 16,11913,I showed and described a machineof asimiliarv nature. but With the additional advantage that the beads'could be attached not only in a straight line' but in any desiredformation.

VThe present invention isiadapted for the samel general purposes asVther machinesl of my said prior patents. In thepresent machine l haveprovided additional features which insure the regular and unfailing.feedingof the beads and their advancement-to the point oftheirattachment tothe fabric.

One branch of my invention relates to the means for `primarily, holdingback the beads from the source of supply'and for allowing them toadvance singly'towardthe stitching mechanism. This branchl'of myinvention is intended to provide a simpl'e'and eflicient automaticdevice for feeding or separatingv the beads as they first leave the'source of supply in order that the operator will not be obliged to Igiveany attention to' thefeeding of the beads Where the stringof beads movesinto the'vertical position, during the operation of the stitchingmechanism. This preliminary feeding or separating device is' `PatentNo.1,073,344,

preferable in order that the Whole supply of beads shall not rest uponor collect in too great numbers near the final separating 'device andthe stitching mechanism. This'preliminary feeding-or separating devicenot onlyV regulates or "controls the separation of the beads Yas theyleave the source'of supply Y but it also assists in the: feeding oradvancement of the beads as they areseparated. A

The final separating' rdevice is not` only adapted to separate the beadson their thread as they approach the stitching position but it isintended to positively move the beadsv down to the'pint of attachment-tothe .fab-

ric, so that the beads Will not be .heldb'ack by any friction on the'thread but each one ivill beA advanced to'fin'al position in proper'time in relation'to the stitching o'perations u Thisbranchof theinvention is disposed tol operate on the beads between the final sepa-vrating device (if more thanoneseparating.

device is used) kand the fabric `and it is preferably so constructedthat the action of the thread loo-per vvill cooperate? tofeed the-`beads to the fabric.

Another feature of improvement relates to the lfilial bead 'separator'and this is' intended to rprevent the beads frompas's'ing the separatorexcept as intended, even -if-the thread should'become momentarily slack.

1,073,344 and in so-pfai" as the rparts in the present case correspond.with vthose of said' primary sepais an elevation yof the principal' vpatent they are similarly numbered. Tn-

asmuch as the present invention may be applied to a machine like that ofsaid` Y such parts as may be necessary to the proper understandingV ofthev additional or substituted features. Y i

Asis set forth in my said Patent No. 1,041,780 the machine Vis intendedto attach strung articles, such as beads, to a fabric by stitches, andas set forth in my PatentNo. 1,073,344 the machine may be employed toattach the articles either in straight lines or in any other formation.V

In the present case VI have shown an upright rod 98 near the right handend of the machinev and supported from `,the frame thereof. This rodforms a support'for a bracket 99 which isradjustable thereon; and forV asecond bracket 100 which is also adjustable thereon. The bracket 99carries the forks 101 provided with anY arbor 102 on which the reel 103with the supply of thread and beadsis adapted to revolve. A frictionshoe 104'Y is pressed against the reel 103 to vput a slight tensionthereon to prevent the reel from turning yfaster than required to letofi" the string of beads. The beads 26 are yloosely strung on a thread26""L and the strung beads on the reel 103 are intended to furnish Vthesupply necessary for the operation of the machine. Y

The bracket 100 forms one of thefsupports (the upper one) for a trough105 which guides the beads fromthe reel 103 to a point Vover thestitching mechanism. There is a bracket 106 fixed to the machine framenear the left hand end, andat its top there is arranged a stationary arm107 which -forms one of the supports for the trough. n

The trough 105 is intended to form a guide and support for the beads. Ithas upright side walls 108 spacedsuiiiciently to receive the largestbeads likely to be used, and

it `has a V.shaped bottom 109 which will cause the string of beads tocenter in, the trough so that they will approach the primary separatingdevice in Vregular order, i. e., in a row. Y

The device for primarily separating the beads upon theirl threadconsists of the following: Y

The bracket 106 has a bearing for a shaft 110 and the latter has an armV111 fixed thereto andeXtending outwardly. A link 112 is fulcrumed tothe arm 111 at one end and at its other end it is fulcrumed to anarm 6()whichl is an extension of the lever arm of theV lever 60-62 of my *saidVPatent fNo.V 1,073,344.v As this lever is operated periodically Vby thecam 48 on the main shaft 3, the

arm 60 operates the link 112 and thus rocks the shaft 110 intime withthe stitching operations of thevrnachine. It is to be understood thatthe arm 60 in the present case' is used to move thev shaft 110in'addition to the function which it performs in'my said patent. Y

There are fixed on the shaft 110 twO, plates 113 and 114 one lying inadvance of the other a distance equal to the length of an individualbead. The inner edges 115 of these plates break joint or are arranged inoverlapping planes and each plate has an arcuate slot 116 curvedconcentrically with the shaft 110. These slots extend from the edges 115of the plates andeach is wideV enough to allow the bead thread to passkY position, viewing the parts in plan, then the bead thread will extendfrom the trough 105 'j through slot 116 in the plate 114 and thelowermost bead will rest vagainst the Yplate 114 (the remaining Vbeads`resting against this lower one) and the inneredge 115 of Y the plate113 will `be in line with the rear end of the lowermost bead. If theshaft 1104 is now rocked toimove the plates 113, 114 to Y the right, theplate 113, will cutkin between thevlowermost bead (the one just heldbackby the plate 114) andthe bead just behind it. The beads in the troughwill now be held back by the plate 113 instead of the plate 114, andwhen the latter moves toward the righty hand position it will havecleared the lowermost bead. Y The latter being no longer held back, willmove down on the thread. Upon the reverse motionA of the shaft andplates, 113, 114 (toward the Vleft when viewed. as in Fig. 3)- then theplate 114 will again straddlethe thread and come into the path of thebeads; andthe plate113' will withdraw from ,the path of the beads,allowing them to move down against the plate 114. Each time the plates113, 114 make a complete movement to the right and left .a beadisrallowed to pass intheV manner described, but only one'eanV pass asthe others are held back. If two or more beads are to be fed at eachoperation it is only necessary to separate the plates 113, 114 so thatthe one lies behind the other the length of two or more beads The beadthread leads, from the upper separator to a novel guidingdevice whichpermits the thread to change to a vertical or nearly vertical direction.On the bracketV 10G there is' iiiied an arm 117 which extends around theseparating device andfwhich has its free end 118 extending-at rightangle to the bead thread. There is anA idler 119 mounted on the end 118and adapted to beturned freely, by the beadthread; rIfhis idler hastransverse groovesv 120 which may be spaced to correspond substantiallywiththeA length of a beadY and it has a peripheral groove 121 in whichthe thread may lie.

As the threadtravels 'around the'idler 119;.

' thread and throughtheshaft STtowardthe stitching mechanism.

rlhe lower separator which. is associated directly with the stitchingmechanism may. beoperated in a similar manner to the separator in saidPatent No.'1,073,344. There is an annular ring 69 which is supportedfrom the'bracket 69a and this ringv formsa bearing for theseparatorlplate 73. The lat-- ter includes` an annular ring portion` 66which Ahas gear teeth 67 on its upper surface and the gear 90 on theshaft 89 is adapted to act on these teeth for the purposeof revolvingthe separator pla-tete corespond with the changes in the directionofffeedfof the fabrieand the changes in the direction of stitching. Thegear 90 may be connected to and operated bythe same actuating devices asthose shownv in my said later patent to operate the presentv separatorin a similar manner and for the same purpose that the separatori-isoperated in my said`v later patent. Y The separator inaddition to thering- 66 has an inwardlyV extending neck 'T2 which carries the inner.plate 73. The latter has a central. aperture 73a `into which the sewingneedle or hook 10 may pass. The outer edge 122 ofthe plate 73 iscircular for the greater portion of itscircumference, preferably con-Ycentric with :the path ofthe needle, and itv Y extends inwardly at 12?from the circular portion. separating a beadbetween successive stitchescomprises a plate 124 secured to the plate 73 and below the uppercircular edge-122 of-fthe latter. The distance ofthe plate12t below thatof the edge 122 corresponds with the length of a singlef bead Viflonebead is to be fed after each` stitch, or,' if two or more beads are .tobe fedvafter each stitch then the plate 124 will be lowered accordingly.This plate 124 lies under the-.cut away portion 123 ofthe plate 73 andit is. slotted at 125 to provide the supporting portion 125^and an outersupporting portion 126.

The under side ofthel plateTS, Iis provided with means for advancing thebeadsdown along-their. thread and ,itis` arranged to act*v on the beadsbetween the separator` andfthe.

ispreferably'the sameasthat shown in my saidv Patent No. 1,()731t` Vandit may .be4 operated by the same mechanism and: for more detaileddescription thereof reference may be had to said patent.

The sewingvneedle or hook 10 shownhere-y iii-may be operated the samemanner asin-my said laterA patent and in sofar as the operating partsare sho-wnlh'erein they-are lettered'` the same .as-insaid patent.

I have previously setforth the. operation of .the primary feeding andseparating device and I will here .set-forth the` operation of thoseparts which finally separate and feed the beads.V l l TheV looper body23V is o'scillated by the complete revolution and-,the looperoscillations are controlled according to the change in the directionoffeeding of the fabric, by

revolving the shaft 28 in the manner set forth in my said later patent.understood that the'worm 271opera'tes ona Worm 22-on the looper body23the same as been made in, the fabric, each complete op` erationof'the'machine may be traced as follows: The beads, generally at Aleast.several in number, which have been fedto the vertical run of: thethreaddrop down so that the lowermostbead rests on the plate "73 lor theplate V124 andi several others rest ldown'on the lowermostbead. If thedelivery end 'of' thelooper25- is near the inner end of the. slot 125yin the plate 124the beads will rest on this plate, the thread leadingVfrom the yend of the looperthrough the slot 125' and to the point 0f thelast, stitch in the- At about this moment* or immedi-l fabric.l atelyafter,the .sewingfhoolr 10 is Lmoved upwardly through the fabric 'andintoA the aperture 73a.

A Vworm 27'which reciprocates with thesha-'ft- 28., so that it makessomewhat less than a;

loop the thread around the sewing hook 10. The latter will then bewithdrawn downwardly through and out of the fabric, forming a switch. Onthe return oscillation ofv the looper theV thread will be carried aroundthe circular edge 122, countercloclrwise, from the point 132 to thepoint 131 within the slot 125. When the first or clockwise movement ofthe looper takes place, the lowermostbead is resting on the plate 124and when the thread commences to rest against the circular edge 122 ofthe plate 73V this edge cuts in between the lowermost bead and the onenext above it and as the lowermost bead slides off the plate 1211 it isno longer Vsupported and it isfree to travel down the thread to thefabric below.` Thesucceeding beads, however, are supported on the edge122 of the Vplate 73 while the looper is completing its oscillation backand forth around this plate. A's soon as the lowermost bead referred tohas been cut off or separatedrby vthe'edge 122 it may slide down thethread asV above set forth, but if it should not drop immediately of itsown weight'it will be engaged by the cam edge 128 and as the loopercarries the thread around the edge 122 the edge 128, acting somewhatlike a cam, will force the separated bead down the thread so that itarrives at its pointl of attachment to the fabric by the time the loopercarriesthel thread to the point 132. This insures the positive feed ofthe bead to rits point of attachment at the proper time.

In theA embodiment of my invention shown herein no action to feed thebead downwardly is required other than `the action of the looper incastingz the loop around the sewing hook and the cooperation of the camedge 12S; so that thevdevice is not complicated by cumbersome mechanism.

Vhen the looper makes its return'movement from the point 132 to the'point 131 the beads above the separator will first rest on t the edge122 of the plate 73 and then they will drop one bead length andbesupported by the plate 12a until the commencement of another operationof the looper. At each complete oscillation of the looper the abovedescribed operations will be repeated. After each stitchthere Awillbe abead fed down the thread to the fabric so that each bead will liebetween successive stitches, thefsamev be a slight thrust of thebeads asthe looper reaches the slot 125 the beads will not be cast off thesupport 73 and travel down' the thread other than as intended.

vExcept as herein set forth theinachine as a whole may be constructedand operated as set forth in mysaid patents. i
